Value streams are central to lean thinking, agile practices, and business transformation. They represent the flow of activities required to deliver value to customers, from idea to delivery. Understanding value streams requires familiarity with the terms, roles, tools, and principles that define how organizations design, manage, and optimize them.
This Value Stream Glossary provides over 100 key terms with simple explanations to help project managers, agile coaches, product leaders, and business stakeholders build a stronger foundation in value-driven delivery.
